If you want to keep the cowl, you need to use the 2-piece shroud.
Fit the bottom hose and the lower part of the shroud.
Remove the fan.
Position the rad onto the lower mount.
Put a rectangular piece of cardboard against the rad to protect the rad and your hand.
Position the fan and bolt it in place.
Fit the bottom hose onto the pump.
Fit the top part of the shroud, the steady bracket and tighten the fan belt.
Thanks... but I've already taken the shroud out. However, I'm just negotiating on a Mk1 Countryman which would be an as-original resto if I'm brave daft enough to take it on... so your advice might still come in handy.
